    Can anyone comment on the safety of using Alrex long term? My doc has
    started me on it for mild (but annoying) dry eye. The idea was to use
    it twice per day for a month, then if things are good, taper down to
    once or twice per week indefinitely. If things aren't all better, we
    could then go on to Restasis. I'm finding conflicting information
    on-line regarding the risk of cataracts from Alrex long term, but maybe
    twice weekly usage is no problem? I'm assuming the initial month is no

    It's preserved with Benzalkonium Chloride ("BAK")

    BAK is horrible for eyes, cytotoxic to corneas (kills off the healthy
    cells), and CAUSES dry eyes in people with otherwise healthy eyes.

    For people WITH dry eyes ... you may as well use Drano, instead.

    Avoid BAK whenever and wherever possible.

    I was told if I had significant improvement he'd recommend using it
    once or twice per week indefinitely ("forever"), in lieu of restasis.
    I'm just the patient, so I don't know whether this is actually a good

    Is restasis preferable for long term use? The thing he told me that
    I'd never read or heard before is that restasis causes permanent
    changes if it works and you eventually taper down and stop taking it.
    Like it fixes you permanently. Is this right?

    Regarding BAK, I don't know what to think about it. I know people over
    at Dry Eye Talk forum are always concerned about it, but why would
    these companies continue to use it if it amounted to poison for the

    It's cheap, readily available, already FDA approved, and DOES do a
    nice job of killing bugs that can spoil/taint ophthalmic drops.

    I tried to petition the FDA to re-visit their approval of BAK. What
    they sent me amounted to a ~200 page application for review that
    needed to be filled out before they would look at it.

    They won. I threw it away.

    If you do the research (PubMed, for example), you'll find LOTS of
    studies that confirm my comments, though.

    It's evil. I would only use it short-term, and ONLY IF there were no
    alternative (eg, an antibiotic drop).
